      BACKGROUND: Radical surgery via total mesorectal excision might not be the optimal first-line treatment for early-stage rectal cancer. An organ-preserving strategy with selective total mesorectal excision could reduce the adverse effects of treatment without substantially compromising oncological outcomes. We investigated the feasibility of recruiting patients to a randomised trial comparing an organ-preserving strategy with total mesorectal excision.

      METHODS: TREC was a randomised, ...

      OBJECTIVE: To describe national reoperation rates after elective and emergency colorectal resection and to assess the feasibility of using reoperation as a quality indicator derived from routinely collected data in England.

      DESIGN: Retrospective observational study of Hospital Episode Statistics (HES) data.

      SETTING: HES dataset, an administrative dataset covering the entire English National Health Service.

      PARTICIPANTS: All patients undergoing a primary colorectal resection in England ...

      Summary Background Long COVID, describing the long-term sequelae after SARS-CoV-2 infection, remains a poorly defined syndrome. There is uncertainty about its predisposing factors and the extent of the resultant public health burden, with estimates of prevalence and duration varying widely. Methods Within rounds 3–5 of the REACT-2 study, 508,707 people in the community in England were asked about a prior history of COVID-19 and the presence and duration of 29 different symptoms. We ...

      OBJECTIVE: To determine the difference in in-hospital mortality and length of hospital stay (LOS) after esophagectomy between the United States and England.

      BACKGROUND: Since 2001, complex procedures such as esophagectomy have been centralized in England, but in the United States no formal plan for centralization exists.

      METHODS: Patients who underwent esophagectomy for cancer between 2005 and 2010 were identified from the Nationwide Inpatient Sample (United States) and the Hospital ...

      Abstract Background The highest-ever recorded numbers of daily severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections in England has been observed during December 2021 and have coincided with a rapid rise in the highly transmissible Omicron variant despite high levels of vaccination in the population. Although additional COVID-19 measures have been introduced in England and internationally to contain the epidemic, there remains uncertainty about the spread and severity ...

      BACKGROUND: The National Reporting and Learning System (NRLS) collects reports about patient safety incidents in England. Government regulators use NRLS data to assess the safety of hospitals. This study aims to examine whether annual hospital incident reporting rates can be used as a surrogate indicator of individual hospital safety. Secondly assesses which hospital characteristics are correlated with high incident reporting rates and whether a high reporting hospital is safer than ...

      REACT-1 is a community survey of PCR confirmed swab-positivity for SARS-CoV-2 among random samples of the population in England. This interim report includes data from the fifth round of data collection currently underway for swabs sampled from the 18th to 26th September 2020.

      PURPOSE: This study compares primary resection with anastomosis and Hartmann's procedure in an adult population with acute colonic diverticulitis.

      METHODS: Comparative studies published between 1984 and 2004 of primary resection with anastomosis vs. Hartmann's procedure were included. The primary end point was postoperative mortality. Secondary end points included surgical and medical morbidity, operative time, and length of postoperative hospitalization. Random effects model was used ...

      BACKGROUND: Trends towards day case surgery and enhanced recovery mean that postoperative venous thromboembolism (VTE) may increasingly arise after hospital discharge. However, hospital data alone are unable to capture adverse events that occur outside of the hospital setting. The National Institute for Health and Care Excellence has suggested the use of primary care data to quantify hospital care-related VTE. Data in surgical patients using these resources is lacking. The aim of this ...

      OBJECTIVES: To evaluate how the World Health Organization (WHO) surgical safety checklist was implemented across hospitals in England; to identify barriers and facilitators toward implementation; and to draw out lessons for implementing improvement initiatives in surgery/health care more generally.

      BACKGROUND: The WHO checklist has been linked to improved surgical outcomes and teamwork, yet we know little about the factors affecting its successful uptake.

      METHODS: A longitudinal ...

      Abstract Background England experienced a third wave of the COVID-19 epidemic from end May 2021 coinciding with the rapid spread of Delta variant. Since then, the population eligible for vaccination against COVID-19 has been extended to include all 12-15-year-olds, and a booster programme has been initiated among adults aged 50 years and over, health care and care home workers, and immunocompromised people. Meanwhile, schoolchildren have returned to school often with few ...

      REACT-1 measures prevalence of SARS-CoV-2 infection in representative samples of the population in England using PCR testing from self-administered nose and throat swabs. Here we report interim results for round 6 of observations for swabs collected from the 16th to 25th October 2020 inclusive.

      BACKGROUND: Patients are increasingly rating their family physicians on the Internet in the same way as they might rate a hotel on TripAdvisor or a seller on eBay, despite physicians' concerns about this process.

      OBJECTIVE: This study aims to examine the usage of NHS Choices, a government website that encourages patients to rate the quality of family practices in England, and associations between web-based patient ratings and conventional measures of patient experience and clinical ...

      OBJECTIVE: Using meta-analytical techniques, the study compared postoperative adverse events and functional outcomes of stapled versus hand-sewn ileal pouch-anal anastomosis (IPAA) following restorative proctocolectomy.

      BACKGROUND: The choice of mucosectomy and hand-sewn versus stapled pouch-anal anastomosis has been a subject of debate with no clear consensus as to which method provides better functional results and long-term outcomes.

      METHODS: Comparative studies published between 1988 ...

      OBJECTIVES: To determine the proportion of avoidable deaths (due to acts of omission and commission) in acute hospital trusts in England and to determine the association with the trust's hospital-wide standardised mortality ratio assessed using the two commonly used methods--the hospital standardised mortality ratio (HSMR) and the summary hospital level mortality indicator (SHMI).

      DESIGN: Retrospective case record review of deaths.
